Description

The absorbefacient disposal type incontinence diaper that has the lateral areas section
The present invention relates to a kind of absorbent incontinence goods of style of opening; It has major part; This major part is made up of forefoot area, rear region and betwixt, between the shank of user in a longitudinal direction crotch region; Wherein major part comprises absorber; And this incontinence articles have join rear region in both sides and/or join on the forefoot area, be provided with the lateral areas section of closing device independently of one another, side longitudinal edge and forefoot area and rear region that this lateral areas section extends beyond major part in a lateral direction are connected to each other in the state that these goods are worn.
This incontinence articles is known and for example in WO 2005/102241 A1, describes.Sometimes the lateral areas section that is also referred to as ear preferably directly joins on the framework of major part, hygienic articles in cutting/laying method.This manufacturing technology allows to make the lateral areas section by the raw material of the middle major part that is different from hygienic articles.For example, the lateral areas section can be implemented ventilatively, and middle major part makes up on liquid-tight ground basically.
From make angle the most effectively and shape the simplest and the lateral areas section that cost is the cheapest be rectangular shape.The material that this shape allows to form the lateral areas section is during fabrication carried with successive flat material strips, and the lateral areas section is separated from this flat material bar transverse to machine direction subsequently.In fact do not exist at this and to cut out waste material.
Yet certified is that when especially favourable rectangular in form made up the lateral areas section under with other situation, when dressing and wearing hygienic articles, can have following problem once in a while: the lateral areas section that is engaged can be torn in the extrorse zone of the lateral longitudinal of major part.What promptly shown is, user tilts when dressing hygienic articles, will be applied on the lateral areas section with the pulling force that longitudinal direction tilts with respect to the horizontal direction of hygienic articles, this in Fig. 1 usefulness obliquely arrow of inclination show.Like this, can occur the lateral areas section along the lateral longitudinal of major part to marginal laceration, wherein the transverse edge towards crotch region of crack section from the lateral areas begins.What once attempted so far is according to WO2004/017882 A2 and WO 02/17843 A2, to improve the joint of this lateral areas section to the major part of hygienic articles through the engaged mode of optimizing.
Another suggestion known in the prior art is; The lateral areas section is provided with intensifier; This intensifier makes up narrowlyer than corresponding lateral areas section in a lateral direction; And this intensifier is arranged in the extrorse zone of lateral longitudinal of crossing over major part at least, and the lateral longitudinal that promptly not only covers major part is to marginal area but also cover the part (DE102006050971A1) of lateral areas section in the horizontal.
The present invention is based on of task is a described problem above solving effectively, promptly propose to have from anterior and from the rear portion attached absorbent incontinence goods with the lateral areas section that engages in two sides respectively, wherein significantly improved the tearing toughness of lateral areas section.
Under the situation of the absorbent incontinence goods that start said type; This task solves through following mode according to the present invention: the rear portion side section is tilting to move towards ground or curved ground structure with respect to longitudinal direction at least on the side of crotch region; Be used to form section leg opening zone, lateral areas; The section leg opening zone, corresponding lateral areas of rear portion side section has the length-width ratio R=A/B of 0.1-0.4 in addition; The tearing toughness Fm of material on the diaper longitudinal direction that forms the rear portion side section in addition is 4.0N at least, and near the closing device the leg opening is maximum 5.0cm apart from the distance C towards the lower limb of crotch portion of rear portion side section.R, Fm and C are determined as further described below in the case.
As following also to set forth and prove, the contoured of lateral areas section has caused lateral areas section tearing toughness to improve significantly because under the situation of the shape of contoured, the lateral edges of major part is inappropriate for the limit of tearing of a type of forming the lateral areas section.In addition, the tensile force through near the introducing of the closing device leg opening lateral areas section when dressing diaper is distributed on the bigger face, and the power that acts on the key point that obtains obviously reduces.Key point is interpreted as following point: the lower limb of lateral areas section is run into the lower edge of major part at that point.
The very little Aspect Ratio R=A/B in section leg opening zone, lateral areas has been enough to produce in this regard significantly useful effect.And it is can be to the wearing comfortableness of disposal type incontinence diaper and fit harmful and improved the amount of cutting out waste material that will abandon greater than 0.4 value R.
What have recognized that in addition is; Form the lateral areas section material be merely at least that the tearing toughness of 4.0N combines the contoured according to lateral areas of the present invention section, allow closing device very closely, that is to say at a distance of being positioned on the lower limb of rear portion side section at most 5cm.Reduce along with the distance of closing device lower limb of section to the risk of marginal laceration along the lateral longitudinal of major part although have recognized that top described, lateral areas section, yet follow the very big loss that occurs on the comfortableness thus simultaneously: have at the diaper longitudinal direction and the diaper of the lateral areas section of the non-in a lateral direction constant width of diaper ground stretching, extension and dress snugly apart from the lateral areas.The wearing next to the shin of diaper can by very closely on the lower limb of lateral areas section localized closing device come obviously to realize more simply because can pulling force be applied on the almost whole lateral areas segment length through closing device thus.Surprisingly, the present invention has solved this not known target conflict as yet through the characteristics combination that specifies in the claim 1.In addition, the motility of the high level when the present invention can be implemented in the material of selecting the rear portion side section has high wearing comfortableness and the material of low tensile strength (tensile strength) because also can use thus.
